Abstract
Mathematical Methods for Economists is a two-semester course for the second year students studying at ICEF which specialize in “Mathematics and Economics”. This course is an important part of the bachelor stage in education of the future economists. It has give students skills for implementation of the mathematical knowledge and expertise to the problems of economics. In the fall semester this course is is dedicated to “Multivariate Calculus and Optimization” (MCO). MCO continues beyond and from January onwards incorporates also the chapters of “Methods of Optimization” course.
